詳細(xì)信息

塑料拉伸沖擊性能試驗機(jī)

液晶屏顯示拉伸沖擊試驗機(jī) 指針式拉伸沖擊試驗機(jī) 塑料拉伸沖擊性能專業(yè)檢測設(shè)備。

用途:

 主要用于在規(guī)定的拉伸沖擊速度下,測定塑料試樣斷裂所需能量的測試。 用于測定塑料等非金屬材料的脆性、韌性。

塑料拉伸沖擊強(qiáng)度試驗機(jī)符合標(biāo)準(zhǔn):

GB/T 13525-92《塑料拉伸沖擊性能試驗方法》

術(shù)語:拉伸沖擊強(qiáng)度:試樣受拉伸沖擊力破壞所消耗的沖擊能與試樣試驗前小橫截面的比值KJ/m2

斷裂伸長率:試樣斷裂后1min時斷裂部分拼接所測得的標(biāo)距相對于原始標(biāo)距的變化率(%)

塑料拉伸沖擊強(qiáng)度試驗機(jī)工作原理:試樣一端固定在擺錘式?jīng)_擊試驗機(jī)的夾具上,另一端固定在丁字頭上,由擺錘的單程擺動提供能量,沖擊丁字頭,使試樣在較高拉伸形變速率下破壞,丁字頭與試樣的一部分一起被拋出,測定擺錘消耗的能量及試樣破壞前后的標(biāo)距,經(jīng)校正,計算得到試樣的拉伸沖擊強(qiáng)度和斷裂伸長率。不同類型或不同尺寸的試樣的試驗結(jié)果不能比較。

 

試驗裝置:

1、試驗機(jī)的擺錘必須為剛性擺錘,對2mm厚的試樣,沖擊時必須使擺錘的物理碰撞中心與試樣厚度中心重合。

2、 試驗機(jī)的夾具不得使試樣被夾破裂和在試驗中滑動,夾爪可有銼刀樣的齒,齒的尺寸可因試樣而異。

3、丁字頭應(yīng)由輕質(zhì)和極低彈性的材料制成,在受沖擊時不得發(fā)生塑性型變。

試樣:試樣由注塑或機(jī)械加工而成。薄膜或薄片試樣可用沖刀裁取。在制樣過程中不得出現(xiàn)試樣過熱現(xiàn)象。如在機(jī)械加工中使用冷卻劑,應(yīng)不影響試樣性能。試樣應(yīng)表面無損傷,內(nèi)部無缺陷,厚度均勻。試樣標(biāo)距的標(biāo)記應(yīng)不影響試樣性能。硬質(zhì)材料試樣不得扭曲。如被測材料各方向表現(xiàn)出不同的拉伸沖擊性能,應(yīng)在不同方向上分別取樣。

試樣形狀和尺寸:試樣厚度優(yōu)先選用1mm。由產(chǎn)品裁取的試樣,保留原厚度;厚度大于4mm的試樣應(yīng)機(jī)械加工為4mm。對于很薄的薄膜,可以使用多層試樣,但應(yīng)重疊良好。

試樣數(shù)量:至少5個試樣或按產(chǎn)品標(biāo)準(zhǔn)的規(guī)定。

 

 

技術(shù)參數(shù):

1)            沖擊速度:3.8m/s 
2)沖擊能量:15J 、25J任選
3)擺錘力矩:pd15J=8.03848Nm pd25J=13.39746Nm
4)擺錘預(yù)揚(yáng)角:150°
5)打擊中心距:395mm
6)使用溫度:(15~35)℃
7)試樣尺寸:長度80±2mm 寬度15±0.5mm 厚度<4mm
夾具間的**長度:30±2mm

2)            電源: 220VAC-15%~220VAC 10% 50HZ (單相三線制)

選擇合適的擺錘使沖擊能量讀數(shù)在試驗機(jī)有效范圍內(nèi),參照下表:

(在能夾緊試樣的前提下盡量選擇質(zhì)量小的丁字頭)

擺錘沖擊能量J

丁字頭質(zhì)量g

15.0

25.0

30±1或60±1

60±1或120±1

塑料拉伸沖擊強(qiáng)度試驗機(jī)試驗結(jié)果的計算和表示:

1、拉伸沖擊強(qiáng)度的計算:

式1

             W

E=                ×1000

        d ×h 

式中:E—拉伸沖擊強(qiáng)度,KJ/m2

W—校正的試樣破壞所消耗的能量,J

d—試樣厚度,單位為毫米(mm)

h—試樣寬度,單位為毫米(mm)

試驗結(jié)果以每組試樣拉伸沖擊強(qiáng)度的算術(shù)平均值表示,取3位有效數(shù)字。

2、能量校正

由于擺錘沖擊試樣所消耗的能量Ws中包括丁字頭飛出所消耗的能量,必須對能量進(jìn)行校正,以求出試樣破壞所消耗的能量。

 

校正的試樣破壞所消耗的能量W按式2計算:

 

 

式2

          W′ W″

W=               

         2

式中:W—校正的試樣破壞所消耗的能量,J

W′—彈性碰撞時試樣破壞所消耗的能量,J

W″—非彈性碰撞時試樣破壞所消耗的能量,J
